• Motor control centres (MCCs) and control panels
• Instrumentation and telemetry systems
• Lighting, earthing, and small power systems
• Prepare design documentation such as:
• Single-line diagrams, schematics, and wiring drawings
• Load schedules, cable calculations, and cable routing layouts
• Control philosophies and I/O lists
• Select and specify components including switchgear, drives, PLCs, and instrumentation.
• Ensure compliance with BS7671 (IET Wiring Regulations), IEC standards, and water industry specifications (WIMES).
• Undertake design risk assessments and support HAZOP/HAZCON reviews.
• Contribute to the integration of electrical and control systems within the overall process design.

Project & Site Support

• Work closely with Project Managers and Mechanical/Process Engineers to deliver coordinated, buildable solutions.
• Provide design support during installation, testing, and commissioning phases.
• Attend client and site meetings to discuss technical requirements and resolve design issues.
• Review electrical installation works for compliance with design intent and standards.
• Support the preparation of O&M manuals and as-built documentation.

Quality & Continuous Improvement

• Ensure all designs meet quality, health, and safety standards.
• Contribute to continuous improvement of design templates, processes, and standard details.
• Support innovation in energy-efficient design and control solutions for treatment processes.

Qualifications & Experience

Essential:

• Degree (or equivalent) in Electrical Engineering or related discipline.
• Minimum 3–5 years’ experience in electrical design for water or wastewater treatment or similar process industries.
• Strong understanding of LV systems, control panel design, and process automation.
• Proficiency in AutoCAD Electrical or EPLAN.
• Familiarity with IET Wiring Regulations (BS7671), WIMES, and other relevant standards.
• Experience producing design deliverables such as schematics, cable schedules, and control philosophies.
• Excellent technical problem-solving and analytical skills.
• Strong interpersonal and communication skills for client and team engagement.



Desirable:

• Experience with PLC/SCADA systems (e.g. Siemens, Allen-Bradley).
• Knowledge of telemetry systems and water industry communication protocols.
• Understanding of ATEX and hazardous area design principles.
• Working knowledge of BIM/Revit for M&E coordination.
• Chartered Engineer status or working towards it (IET or equivalent).

Key Competencies

• Technical accuracy and attention to detail.
• Team-oriented and collaborative approach to problem solving.
• Effective communication and coordination with multidisciplinary teams.
• Strong time management and organisational skills.
• Commitment to health, safety, and environmental excellence.
• Passion for sustainability and innovation in the water industry.
